We can use inverse operations to solve an equation: The opposite of adding is subtracting The opposite of multiplying is dividing. To get b by itself we need to get rid of the 5 At the moment b is multiplied by 5, the opposite of multiplying by 5 is dividing by 5. To get c by itself we need to get rid of the 4 At the moment c is divided by 4, the opposite of dividing by 4 is multiplying by 4. Sometimes the answer to an equation is not a whole number. In these cases we can leave our answer as a fraction. When the unknown what we are working out appears on both sides of the equation, the first step is to get them on the same side.

Solving linear equations means finding the value of the variable s given in the linear equations. It has a degree of 1 or it can be called a first-degree equation. Sometimes, we may have to find the values of variables involved in a linear equation. When we are given two or more such linear equations, we can find the values of each variable by solving linear equations. There are a few methods to solve linear equations. Let us discuss each of these methods in detail.

Here we will learn about forming and solving equations, including how to form linear equations from situations and solve them and how to form quadratic equations and solve them. Forming and solving equations is when we are given a mathematical situation which is, or can be, described using algebraic expressions. We can use the algebraic expressions and information about the situation to form an equation.
